To all whom z'mag/ concern; "i

Be it known that.v LHAROLD HEBERT CAR- TER, a subject of the 'KingofGrreat Britain,

residing at l2 Nutfield` Gardens, lThornton Heath, Surrey, England.,have'invent'ed new' and useful, Improvements in and relating t0 MotorFireEngines andRailV Coaches Y combination beingadapted to serve asanemergency' fire engine tol run upon rails..

We r ovide `one-or both of the axles 'of the lrailivay coach or truckWith an electric motor, the shaft of which preferably parallel with' andadjacent to the.'v axle.

Means are provided such as, toothed Igear orV Vchain Wheels 'forsuitablyI connectingr the shaft of the electric mjotor to theadjacentaxle'in order to drive same. Th'e'leadsor Y Wires for energizingthe saidelectric motor,

or motors, if two are employedgfare passed through `the floor-,ofthecoach-or truck in a lsuitably .insulated 4or protected manner..V

The said coach or truck is made to suitably .open at one end inforderthatfthe motor' fireengine preferably of the petrol elec-v Y trictypemay be run on to the said railway coach or.- truck andV [suitablyscotohed or Y heldthereon by removablebars or theV like.

yWhen theY petrolV electric fire engineI Vis run4 into positionandsecured upon the said coach, -the'leads or Wires before mentionedconnected tothe said electric motor or motors are `vthen connected toV'the dynamo .orV gen-A erator upon the said .road petrol' electric fireengine,..and by'sxvitching means. provided thereon the propellingelectric motor upon lthe said fire .engine is completely. isolated .inVorder that the whole, ofv the .energy Vprovided by theinternalcombustion engineand dynamo `and the said'road ireenglne may beconveyed or transmitted throughsuitable controlling switches to theelectric motor or motors for .driving the said railway coach or truck.

The combinedvehicle as described may then be run alongthe j-rails Ato4the L position i in lwhich it is desired-'to 'operate fon 'the ire'.,

ros l.

The rame'l of the vehicle is extendedat I1, upon which extension issecured 'the pumping unit J comprising the electric motor K and thecentrifugal pump which lil 0 has the inlet L1 and the outlet or deliveryL2 for connecting the hose pipe (not shown) projecting rearwardly. Theinlet is shown capped for travelling. The electric motor and pump aredirect coupled on a vertical shaft. The electric motor K is connected bythe cable K1 to the dynamo B through the control switch K2.

When the vehicle is stationary and it is vswitches H and K2 is closed ata time, the

other being left open.

The railway coach or truck shown is at one end provided with a hingeddoor ,P which is adapted to fall down and to enable Athe petrol electriclire engine as described to be runupon the coach from a platform or fromthe ground by means of an ordinary ramp, not shown. "When the lireengine is lsecuredin position on the motor coach the plug connector Q ofthe cable R is inserted.

'The cable R is connectedto the control switch R1. 'The connection ofthe dynamo B with the electric motors C and Kis then broken by means ofthe switches H and K2 y respectively so that these are isolated. Theswitch B1 is then operated in order to complete the circuit and thecurrent then flows from the dynamo B by the cable R2 to the electricmotors S, S1, to energize both Yof them equally. The electric motors SS1, are each so arranged adjacent the two railway truck axles T, T, andparallel therewith that the electric motors S, S1, may drive the tworail lianged wheels U, U, by means of the spur gear wheels V, V, whichare keyed to the `arles T, T, andv spur pinion wheels W, l/V, which karemounted upon vthe shafts of theelectric motors S, S1, the speed controlbeing effected by means of the switch R1. The brakes and the otherapparatusof the railway coach are of the usual kind. The 'switch R1 vismounted in a convenient position for the driver of the vrail motor coachadjacent the usual brake lever.

When the -Y rail coach thus driven has reached the vscene of the fire,the electric pumping unit JV may beY operated if desired with. thepetrol electric .tire engine mounted in position as shown on the railwaycoach by breaking the connection by means of the switch R1 of the dynamoB to the motors S, S1, and connecting the dynamo as before described tothe electric motor K. 0r the petrol electric lire'engine may be run offthe railway coach to the scene of the fire by energizing the electricmotor C as before described in the usual way.

The flexible hose pipe to the fire engine is carried within the body O.l It will be understood that the whole of the electric energy providedby the dynamo B coupled direct to the internal combustion engine A isconveyed to one only of the driving usesV for which this electricalenergy may be employed, viz. lirstly ,it may ener- ,gize the electricmotor driving the petrol electric vehicle, or secondly, the electric mogtor K ofthe pumping unit J, or thirdly, the

kelectricmotors S, S1,"serving`to drive the railway coach shown, that isto say, thatk when the current ofthe dynamo B is employedfor one of thesaid purposes, it is completely Vswitched off from the other two.

Y VVhat'Tfdo claim as my invention and desire to secure by LettersPatent is5 1. A rail coach or truck adapted to carry a road electricmotorv fire engine and to re- Yceive electric energytherefrom forpropulsion.

A 2. The combination witha road motorvehicle, having a prime mover andadynamo as a power unit, of a rail carriage propelled by said dynamo'.l

3. The combination with a road motor vehicle having Va power unit in theform of a prime mover anda dynamo, and. a pump adapted to be `operatedfrom said dynamo, of a rail carriage' adapted to be propelled from thedynamo. Y

4. The combination with a road motor vehicle having a powerunit `in theform of a primemover and a dynamo, and a pump adapted to beoperated'from said dynamo,

vof a rail carriage having an electric motor associated with the aXlethereof, said Amotor adapted to be energized from the dynamo.

y 5. The combination with a road motor vecle having a power unit in theform of a prime mover and` adynamo, and a pump adapted to be operatedfrom said dynamo, of a rail carriage having an electric motor associatedwith the axle thereof, said motor adapted to be energized from thedynamo, and switching and connecting means whereby the electric energysupplied by the dynamo may be directed for propelling the road vehicle,for operating the pump, or for propelling the rail carriage.
